TUCKlNG-GUIDE FOR'SEWINGIMACHINES.

SPECIFICATION forming part of Letters Patent N o. 691,705, dated January 21, 1902.

Application filed February 15, 1901. Serial No. 47,401. (No model.)

To @ZZ whom it may concern:

Be it known that I, CHARLES H. LEWIS, a citizen of the United States, anda resident of Syracuse, in the county of Onondaga, in the State ofY New York, have invented new and useful Improvements in ing-Guides for Sewing- Machines, of which the following,

taken in connection with the accompanyingl In the annexed drawings, Figure 1 is a plan view of a tucking-guide or tuck-folding attachment embodying my invention. Fig. 2 is a horizontal section on line X X in Fig. l.

Similar letters of reference indicate corresponding parts.

a. denotes the stay-plate of the tuckingguide. This plate is formed with a gagiugshoulder b, consisting, preferably, of an upwardly-bent portion of the plate a to simplify and reduce the cost of manufacture. From the top edge of the shoulder b extends at right angles a horizontal .tongue c, which is also preferably formed integral with the aforesaid shoulder, and thus allows the three members a, b, and c to be formed in one piece stamped out of suitable sheet metal.

On the under side of the tongue c is carried a shoe d, which is movable lengthwise of the tongue and adj ustably clamped in its required position by any suitable means, preferably by jaws d', formed on the shoe and engaging opposite edges of the tongue cand provided with inwardly-bent lips d2, bearing on top'of the tongue and holding the shoe snugly on the under side of the tongue, which latter is provided with a plurality of downwardly-projecting spurs e, distributed lengthwise ofthe tongue and adapted to engage an indentation e in the underlying portion of the shoe.

f represents the coperating gaging-shoulder, which projects downward from the shoe and is preferably formed integraltherewith.

The aforesaid construction allows the gagingshoulder f to be adjusted to the requisite distance from the shoulder b to form on the fabric a tuck ofthe desired width.

For fastening the stay-plate et to the table of the sewing-machine I employ the attaching-arm g, which is formed in one piece with the laterally-extending supplemental arm g', provided with a longitudinal slot for the reception of the attaching-screw j. The stayplate d is formed integral with a rectilinear guide h, disposed parallel with the gagingshoulder b and extending lengthwise of the attaching-arm g, on which it is supported by lips formed on the guide h and embracing the longitudinal edges of the arm g, as clearly shown in Fig. 2 of the drawings. The stayplate is thus allowed to be shifted longitudinally on the attaching-arm g` to carry the tongue c a greater or less distance from the front of the sewing-machine needle n, as may be desired.

The gaging-shoulder b is rendered adjustable in its distance from the side of the needle n by the longitudinal slotc' in the supple- 'mental 'attaching-arm-4g, which is integral with the arm g and clamped adjustably on the table by the attaching-screw j, passing through the slot z', as hereinbefore described.

The stay-plate is retained in its desired position by one of a plurality of spurs on the under side ofthe arm g engaging an indentation in the underlying guide h substantially in the same manner as the retention of the shoe clon the tongue c. f

What I claim as my invention is The combination with the attaching-arm, of the stay-plate formed with a guide provided with lips embracing the edges of said arm and adj ustably clamped thereon, a gaging-shoulder formed on said plate, a tongue extending from said shoulder, a shoe adjustably sustained on said tongue by jawson the shoe engaging the edges of the tongue and by a spur on one engaging an indentation in the other of said parts and a gaging-shoulder projecting from said shoe substantially as set forth and shown.
